[0024] see figure 1 , the first embodiment of the present invention provides a brightness adjustment method applied to a mobile terminal, the method comprising:

[0025] Step 101, acquire the ambient light of the first camera of the mobile terminal and the user's age information in the preview frame data of the first camera.

[0026] Wherein, the first camera of the mobile terminal may be a front camera or a rear camera. The preview frame data of the first camera is the frame data of the preview interface of the first camera, and the age information defining the user is acquired from the preview frame data. Ambient illuminance is commonly referred to as lux, which means the luminous flux per unit area of ​​the surface of the subject (refers to the radiation power that the human eye can perceive).

[0027] Step 102, determine the brightness level of the soft light of the mobile terminal according to the ambient light intensity and the age information of the user.

Abstract

The invention provides a brightness adjustment method and a mobile terminal. The method is applied in the mobile terminal, and comprises the following steps of acquiring the ambient light of a first camera of the mobile terminal, and age information of a user in preview frame data of the first camera; confirming a soft light brightness level of the mobile terminal according to the ambient light and the age information of the user; adjusting the soft light brightness of the mobile terminal according to the soft light brightness level. According to the brightness adjustment method and the mobile terminal provided by the invention, the ambient light and the age information of the user are comprehensively considered, so that the soft light brightness can be adjusted, a photographing effect is ensured, and meanwhile, the aim of protecting eyes is achieved. The problem that the soft light brightness of an existing mobile terminal is generally fixed, so that the soft light brightness cannot be adjusted according to the fill-in light intensity required by the environment where a photographer is located and the self-condition of the photographer is solved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a brightness adjustment method and a mobile terminal. Background technique [0002] As various electronic devices gradually enter people's lives, smart electronic devices, such as mobile phones, have become the main tools for people to take pictures, and users also tend to take pictures through various smart electronic devices. In order to improve the photo taking effect, some terminal devices have set up a light (usually an LED light) next to the front camera to improve the selfie effect in poor light environment. [0003] However, the brightness of the soft light is usually fixed, which may cause the soft light to be too bright in an environment where the light is not very bad or not bright enough in a too dark environment, and cannot be compensated according to the photographer's environment. Adjusting the light intensity and the photographer's own situation cann...
